Abstract: Morada Nova hair sheep show traits desirable for lamb production especially in extensive production systems in Northeastern Brazil, representing an important genetic resource for producing lamb in semi-arid climates in Brazil and elsewhere. Performance testing has been carried out annually with this breed since 2008. In the present study, Morada Nova sheep from two Brazilian states: Ceará (140 animals) and São Paulo (112 animals) were genotyped for a SNP associated with litter size, which is almost only found in Brazilian locally adapted sheep breeds (FecGE). The total observed frequency of FecGE was 0.65, while an increased number of observed heterozygotes was also observed (?2 = 7.274, p< 0.01). No significant FecGE allele frequency... |

Sheep production activities are growing rapidly in Brazil and are based on locally adapted breeds in addition to commercial breeds available internationally. Contemporary methods for genetic management of flocks are in high demand and motivated the work for development of a SNP-based marker panel useful for breed certification, parentage testing and individual identification purposes. |
